In addition to irregular black holes which have intrinsic singularity in the origin of space-time, black hole solutions without space-time singularity were first introduced by Bardeen [1]}–[2]} and later another type of regular black holes was presented by Hayward [3]}. Rotating Hayward and charged Hayward black holes are also constructed in [4]} and [5]}. Similar to irregular black holes studied in the presence of quintessence matter, Nam obtained a static Hayward black hole solution with quintessence matter [6]}. The geodesic motion in the space-time of such a black hole is studied in [7]}–[8]} and extended to the rotating case in [9]}. Also, for studying the shadow of rotating Hayward black holes in the absence and presence of quintessence matter see, [10]}–[11]}. Guo et al. have studied the shadow of Hayward black hole with an accretion flow [12]}. Now, in the present paper, we study the shadow of Hayward black holes surrounded by quintessence matter obtained by Nam [6]}, in the presence of spherical accretion flow; Namely we generalize Guo’s work to the case of accreting Hayward black hole surrounded by quintessence dark energy and investigate the effects of both the magnetic charge and quintessence state parameter on the physical parameters of black hole. We discuss the specific intensity of the shadow and the luminosities of the quintessence Hayward black hole shadow and photon sphere, and also compare our results with the results corresponding to the Schwarzschild, quintessence Schwarzschild, and Hayward black holes.
